Enum PaddingColor 

pub enum PaddingColor {
    Gray(u8),
    Rgb([u8; 3]),
}

Padding colour used during letter-box resizing.

YAML accepts a single integer (grayscale) or a three-element sequence [r, g, b].

Variants

Gray(u8)

Rgb([u8; 3])

Implementations

impl PaddingColor

pub fn as_gray(&self) -> u8

Return the grayscale byte value (uses the first channel for RGB).

pub fn as_rgb(&self) -> [u8; 3]

Return the RGB byte triple.

Trait Implementations

impl Clone for PaddingColor

fn clone(&self) -> PaddingColor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PaddingColor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PaddingColor

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PaddingColor

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PaddingColor

fn eq(&self, other: &PaddingColor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
